As you can tell from the photo above, we still have quite a wait for Marvel’s Avengers: Infinity War and its sequel (the latter of which will no longer be calledAvengers: Infinity War). Christopher Markus and Stephen McFeely are currently hard at work on the scripts, writing them both in tandem. The duo behind the Captain America films discussed where they’re at in the writing process and responded to whether they’ll kill off any characters in the sequels.

Below, check out the latest Infinity War update.

Starting this fall or winter, directors Anthony & Joe Russo will start shooting the sequels, which may take around nine months to complete filming. With the production start date approaching, Markus and McFeely talked about the progress the project is making. They told Yahoo! Movies they’re working on the third draft of Infinity War and draft two of its sequel:

We’re many drafts in. We’re on the third draft of movie one and the second draft of movie two. [We’re writing them in tandem] as much as we can. On any given day, you’re only working on one but that doesn’t mean that next week, you aren’t working on the other one. And certainly, notes are coming in and all sorts of production stuff is coming in, like for instance, ‘that thing over there is now a window not a door so adjust that.’ Or, ‘we’re not going to this town now, we’re going to this town.’ That kind of stuff happens constantly and will continue to happen for the next few months.

As for whether they’ll kill off any characters in the sequels, Markus responded:

When we lock ourselves in a room with the Russo brothers and a couple of execs from Marvel, one wall has cards for movie one and the other wall has cards for movie two and another wall has little baseball cards of every character still alive in the Marvel universe —

McFeely continued with the story:

Down to Darcy’s boyfriend in Thor 2 – literally, anybody who did not die and has been established as alive. And then we looked at that began to shuffle the cards around. So basically, the big scene is when Darcy’s boyfriend and Galactus get together and….[Laughs].

If their Marvel baseball card collection even includes Darcy’s boyfriend, Ian Boothby (Jonathan Howard), then that should give you an idea of how many baseball cards they have left for all the characters still breathing in the MCU. Markus and McFeely were, of course, joking about Darcy’s boyfriend and Galactus ending up in the same room together, but that joke is a reminder of just how many characters the screenwriters have to work with for the sequels.

The Avengers: Infinity War opens in theaters on May 4th, 2018. The Untitled Avengers sequel scheduled for May 3rd, 2019.
